1.7" Ankylosaur Vertebra - Alberta (Disposition #000024-25)

First a note on the legality of this fossil. Alberta has very strict laws pertaining to fossil collection. Fossils may not be removed from the province of Alberta without permission from the government. To gain ownership of a fossil, you must be issued a Disposition Certificate. Currently only a few fossil types are eligible for disposition. These include ammonites, petrified wood, leaves and fossil oysters.

This specimen is part of a collection of dinosaur material that was collected by a single individual (Steve Walchina) decades ago prior to the current law. Because it was collected before the law went into effect, the collection was "grandfathered" in. The collection was reviewed by the Royal Tyrrell Museum and a disposition certificate issued for portions of it that were not considered scientifically significant. This moved the fossils into private ownership and allowed them to be removed from the province. The disposition certificate (#000028-29) is on file with the Royal Tyrrell Museum. This makes the small amount of Alberta dinosaur fossils we recently acquired from this collection some of the only legal Alberta dinosaur material on the market.

This is a 1.2" Ankylosaur, cervical vertebra, centrum from the Horseshoe Canyon Formation, Alberta Canada. This specimen is in good condition. The processes are missing but the example shows good cortical bone in places and anatomical features like fossa are visible. There is a repaired crack.

There are three Ankylosaurs described from the formation including Anodontosaurus, Edmontonia and Euoplocephalus but It is impossible to differentiate species from single vertebrae.

Ankylosaurs were herbivorous dinosaurs that lived during the Cretaceous and evolved complete body armor covered in plates, scutes and spikes. They wielded a massive tail club which could have been used to defensive purposes against predators such as Tyrannosaurs. Adult Ankylosaurs are believed to have reached up to 25 feet in length.
